Amanda, 30, and Thomas first met in 2015 starring alongside each other in the play The Way We Get By, where they played two people getting to know each other after a one-night stand.

Earlier this year, they met up again on the set of comedy The Last Word, which they both star in, and have been dating since then.

Amanda, who was spotted in New York wearing a band on her ring finger last week, previously dated Justin Long and Dominic Cooper, and last year Thomas, 40, split from his wife of eight years, Kimberly Hope.
